1.

You have to be careful when you open a can of mixed nuts in space.

2.

Vegetables come in dehydrated packs, and require rehydration from a special machine before eating.

3.

There's pretty much only one option for haircuts in space, and there's a specially designed hair clipper on the ISS attached to a vacuum to keep hair from floating away.

4.

Washing your hands without a sink requires a pre-packaged pouch of soapy water that you just squirt out and rub on your hands.

5.

Wringing out a soaked washcloth doesn't really do much.

6.

Sleeping in space requires special tethered sleeping bags in little sleeping compartments so you don't float all over the place.

7.

Desserts in space mostly come in pudding form packed in pouches, like this chocolate pudding cake.

8.

You shouldn't cry in space because your tears just hang out on your face.

9.

When you clip your nails in space, you have to do it right over an air duct to keep the clipped nails from flying all over the place.

10.

You cant use any water when shaving, so astronauts use a specially designed shaving cream that helps keep the whiskers from floating away.

11.

When you brush your teeth in space, the only way to get rid of the toothpaste when you're finished is to swallow it.

12.

Astronauts have specially designed barf bags to keep vomit totally contained when they get sick.
